Martha is very meticulous and knows the real principle of electrolysis. She does not pluck hair and makes sure she kills a follicle before she pulls it out. It is very important for me, as I’ve had an experience when electrologists didn’t completely kill follicles and plucked my hair. That was a waste of money. Also, my hair is very light that makes it harder to work with. The atmosphere is very calming and my dog sleeps as Martha works on my hair
